Abstract
THE THICKNESS OF A MIRROR BLANK WILL BE MEASURED CONTINUOUSLY FROM THE BACK SIDE, THUS PERMITTING THE CONTINUOUS REMOVAL OF MATERIAL FROM THE FRONT SIDE WITHOUT THE NECESSITY OF STOPPING WORK PERIODICALLY TO MEASURE THE MATERIAL REMOVED. THE METHOD OF MEASUREMENT EMPLOYS AN "ACOUSTIC MICROMETER" WHICH USES EXTREMELY SHORT PULSES TO ACHIEVE A PRECISION OF A SMALL FRACTION OF A MICRON. TEMPERATURE COMPENSATION WILL BE ADDRESSED.
